Types: Holotype ♂, 3♂ 3♀ paratypesfrom Tunisia, Kebili, Nefzaoua ( N33°23’0” E7°48’0”), Vibert leg., Coll. Simon 12687 (MNHN AR15685); deposited in MNHN.
Etymology.The species name refers to the oval form of the epigynal fovea.
Diagnosis. Males of H. ovatus sp. n.differ from other species by the sickle-shaped embolic apophysis in the male ( Figs 101, 115), females by the oval epigynal fovea, much more elongated than in the related H. signiferand H. pseudosignifer( Figs 105, 116).
Description.Measurements: Male (n=4): Total length 6.2‒8.0; carapace 2.66‒3.44 long, 2.22‒2.44 wide. Female (n=3): Total length 6.8‒8.8 carapace 2.16‒3.14 long, 2.08‒2.36 wide. Colour: Carapace yellowish brown, eye region infuscate; chelicerae, labium and maxillae dark reddish brown; sternum orange brown with darker margins; legs yellowish brown; abdomen pale grey. Spinulation: General pattern, with metatarsi I spineless in all specimens examined and metatarsi II spineless in 1 female. Male palp ( Figs 100‒104, 113‒115): Tibial apophysis as long as the tibia’s diameter, with nearly symmetric margins, with obtuse tip ( Figs 100, 114); embolic apophysis with nearly straight retrolateral margin and strongly curved prolateral margin, at its base half as wide as in the middle, with subterminal prolateral angularity, terminally pointed ( Figs 101, 115). Epigyne ( Figs 105‒106, 116‒117): Hood much wider than fovea, weekly sclerotized, with protruding median margin; pro-fovea narrow; fovea oval ( Figs 105, 116), basal margin with an angularity; lateral pockets elongated, at its base with supplementary pocket ( Figs 106, 117).

Ecology.The species was captured in chotts (inland salt marshes) and in a dry river bed in the semi-arid and arid climate zones of the Maghreb.
Distribution.The species is known from two localities in the Nord East of Algeria, and two localities in central and southern Tunisia(map 3).
